-If time (and functionality above is in place):

    • If a bridge is gone due to bandwidth issues or descriptors not being published, replace them with working bridges in Lox–this will have implications for syncing with rdsys but first things first :slight_smile:

  • (long term)

    • brainstorming grouping strategies for Lox buckets (of bridges) and gathering context on how types of bridges are distributed/use in practice.

  • Question: What makes a bridge useable for a given user, and how can we encode that to best ensure we’re getting the most appropriate resources to people?

    1. Are there some obvious grouping strategies that we can already consider?

  • e.g., by pt, by bandwidth (lower bandwidth bridges sacrified to open-invitation buckets?), by locale (to be matched with a requesting user’s geoip or something?)

    1. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less?
